By manipulating your kombucha, it sometimes happens that it is torn and that it is no longer as beautiful as a whole
"mushroom". This problem is rather aesthetic, because this does not prevent it from constantly producing an additional layer on the surface of the jar that receives it.
The new membrane that forms over the damaged portion of the kombucha will simply be thinner, but after a few generations it will regain its normal thickness.
Sometimes, gas accumulates under the mushroom and pushes the new layer, still thin, above the surface of the liquid: in this case, simply lift the membrane so that the gas can escape. Thus, the membrane will again be in contact with the liquid and will have a more uniform growth.
